PADDING FOR SEAT BACKS.

Original application filed December 26, 1923, Serial No. 682,839. Patent No. 1,650,086, dated November 22, 1927. Divided and this application The present invention relates to improvements in padding for backs of automobile 'seats, or similar upholstery, and the particular object of the invention is to provide apadding that will completely fill an elongated pocket provided for its reception and press the same into cylindrical form, which is particularly adapted to resist wear and to maintain its resiliency-for a long period of time.

It is further proposed to arrange the padding as an individual article, and tense for this purpose two different kinds of materials, the outer shell or sleeve being made of ma- 1 terial of considerable tensile strength, such as long staple cotton, and an inner filling of low tensile strength, such as short lengths of jute, waste cotton, and other shorttibre material. It is proposed to use the filler for forcing the sleeve into cylindrical form, and to also provide a stiffening element which is used to longitudinally reinforce the padding so as to facilitate'its introduction. into a pocket and to oppose bending stresses.

The present application is divisional to application, Serial No. 682,839, Dec. 2(', 192:), Patent No. 1,650,086, Nov; 22. 1927,. a id the device described herein is one of the forms originally presented in the latter application.

so The form desired to be'protected in this application is illustrated in the accompanying drawing, in which:

Figure 1 shows a perspective view of a padding, and

Figure 2 a transverse section through the same.

In the form illustrated in Figures. 1 and-,2 a sheet 1 of flexible material preferably made of long fibre cotton, or other material of con- 40 siderable tensile strength is turned into a sleeve with the edges of the sheet abutting as shown at 2. A stifi'enin strip 3 preferably lying on the outside of the sleeve covers the two abutting edges, and is glued to the same area October 19, 1925. Serial No. 63,291.

for joining them. This strip serves the. purpose of stitt'ening"the entire padding and of facilitating its introduction into a pocket in the upholstery.

The interior of the sleeve is filled with material, shown at 4', less extensive than that ofthe sleeve and preferably consisting of waste cotton, short tibre, jute. or similar low ,Ql'tltlt"llltlt'0ll2ll. This material is forced into the sleeve so as to press the latter into cylindrical form which renders it part'i'culin'ly. adapted to stand long continued pressure without; losing its shape.

1 claim:

1.. A padding material made for endwise introduction into an elongated pocket and comprising, a sleeve made of flexible mate.- rial of considerable. tensile strengtlna fillerot comparatively short fibre pressed into the. sleeve so as to force the latter into cylindrical. form and a stiffening member on the out.- side 'of the sleeve.

2. A padding material made for endwise introduction into an elongatedpocket and comprising a sheet of flexible material oi considerable tensile strength coiled to fornf a sleeve withabutting edges, a strip of stiti'ening material overlying the abutting edges for joining the same, and a filler of comparatively short. tibre pressed into the sleeve so as to force the latter into cylindrical form.

3. A padding material made for endwise introduction into'an elongated pocket and comprising a slieet of flexible material of considerable tensile strength coiled to form a sleeve with abutting edges, a strip of stiffening material overlying the abutting edges on the outside of the sleeve for joining the same, and a filler of comparatively short fibre pressed intothe sleeve so as to force the latter into cylindrical form.
